=== decoding for LG A/C using Arduino ====

• 1. remote of LG AC has two type of HDR mark/space, 8000/4000 and 3100/10000
• 2. to decode use https://gist.github.com/chaeplin/49fb927d8021acbcb6d8b674fd59d986
• sample output using
• bits :32 1000 1000 0000 0000 1101 0000 1101
• bits :28 1000 1000 1100 0000 0000 0101 0001
• bits :32 1000 1000 1100 0000 0000 0101 0001
• bits :32 1000 1000 0000 0000 1101 0000 1101
• bits :28 1000 1000 0000 0000 1101 0000 1101
• bits :32 1000 1000 1100 0000 0000 0101 0001

===== * old info

• 2. HDR 8000/4000 is decoded using decodeLG(IRrecvDumpV2) without problem
• 3. for HDR 3100/10000, use AnalysIR's code : http://www.analysir.com/blog/2014/03/19/air-conditioners-problems-recording-long-infrared-remote-control-signals-arduino/
• 4. for bin output based on AnalysIR's code : https://gist.github.com/chaeplin/a3a4b4b6b887c663bfe8
• 5. remove first two byte(11)
• 6. sample rawcode with bin output : https://gist.github.com/chaeplin/134d232e0b8cfb898860

• 1. Sample raw code : https://gist.github.com/chaeplin/ab2a7ad1533c41260f0d
• 2. send raw code : https://gist.github.com/chaeplin/7c800d3166463bb51be4
